PRINTING-MACHINE.

To all whom may concern:

Be it known that I, iCLAY M. RUNYAN, a citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Printing- Machines, of which I hereby declare the following to be a full, clear, and eXact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a printing machine wherein two printing mechanisms are provided, whereby one of said mechanisms can print certain subject-matter upon each blank and the other of said mechanisms, if desired, can print different subject-matter upon each blank.

One obj ect of the invention is to provide an improved machine of this character capable of operating rapidly and economically.

Another object of the invention is to provide a simple and eilieient printing machine in which opposite sides. of blank sheets of paper, cards, or other blanks may be printed.

'Ihe invention relates to that type of machine described and illustrated in Letters Patent No. 1,025,926, granted to me on May 7th, 1912, for a combined printing` and addressing device. In the machine illustrated in. this patent the main printing device operates upon the upper sides Vof the blanks, and the printing slugs operate upon the lower sides of said blanks. In the present machine however, this arrangement is reversed, but the position of the printing devices, either or botlnrelative to the support or supports for printing upon the blanks can be changed, to suit circumstances of'use or special requirements without departing in any manner 'from the scope of the claims.

The invention is hereinafter further de` scribed, illustrated in the accompanying drawings and particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a plan view of the machine; Fig. 2 is a side elevation of the device showing Athe feeding mechanism lfor the series of printing slugs, the receptacle therefor, the main printing roller and operating mechanism for thervarious devices; Fig. 2a is a detail Specification of Letters Iatent.

In these drawings the machine is exemplified in all essential features but modiieations in relative position and arrangement of the various parts can be made without departing from the scope of the claims.

In the aforesaid drawings 1 is a bed plate of any suitable construction. The bed plate is provided with a platform F upon or over which blanks such as cards C are moved to the different printing positions. 2 is a main longitudinal shaft from which the various movements of the printing and feeding devices for blanks and printing slugs are obtained. The shaft 2 is mounted at its opposite ends in suitable bearings provided in arms which preferably depend from the bed platel. Upon this main shaft 2 is mounted the printing drum 3. A receptacle 4 for printing slugs is mounted at one end of the platform and a second receptacle 5 at the other end of the platform receives the slugs as fast as the impression has been taken from them. One of these receptacles v shafts.

is shown above the platfoim and one below. The printing slugs are fed longitudinally of the machine upon suitable guides 6, 6 from one receptacle to the other by mechanism hereinafter described.

The printing position for the slugs is preferably arranged in the center of the machine underneath a fixed pressurehead or abutment 7. R is a receptacle for cards or other blanks to be printed and they are fed by means of mechanism hereinafter fully described, preferably first to the printing position for the slugs in operative relationship to the fixed pressure head 7, and then to thel printing position of the printing roller 3. i The operation of the feeding and printing mechanism for the printing slugs may be first described as follows:V

rPhe main driving shaft 2 is provided with ya spur gear 9 and a bevel gear 10. The

bevel gear 10 drives a bevel gear 11 on a transverse shaft 12 which in turn drives a short longitudinal shaft 13 by means of the bevel gears 14 and 15 on the respective A lshort central transverse shaft 16 is driven from the shaft 13 by means of the bevel gears 17 and 18 on the respective shafts and upon the shaft 16 are mounted two eccentrics 19 and 20.' The eccentric 20 is employed to operate the feeding device for' the printing slugs, while the eccentric 19 is employed to operate a plunger 21. The plunger 21 serves to press a card C against one of the printing slugs P, which is held meantime immovable by the pressure against the head -see Fig. 5.

The slugs P may be intermittently fed oi' moved to the printing position by meansI of a chain or band 22 mounted upon suitable supporting disks or sprocket wheels 23, 23, arranged near opposite ends of the machine. The wheels 23 are mounted upon transverse shafts 24, 25, which are supported in suitable bearings provided on the frame 1. An intermittent progressive movementV is imparted to one of these shafts as 25 by means of the eccentric 20 upon the centralshaft 16 and a pawl 26 connected to a sleeve 27 upon said eccentric, as shown in Fig. 2, y

The pawl 26 successively engages the teeth 27 of a ratchet wheel 28 upon a transverse shaft 29. v The shaft 29 is preferably arranged parallel with the shaft 25 and may be operatively `connected therewith by means of spur gears 30, 31. Thegears 30, 31, are proportioned to give the necessary amount of movement to the driving sprocket wheel to advance each slug to its printing position opposite the abutment 7 with cach reciprocation of the pawl 26.

The slugs travel between the guide rails 6 and are engaged by the members or pins 32 extending from certain links of the feed chain 22 and moved thereby alongthe guides 6. The guides 6 are provided with shoull Tl ders 6 between which the slugs move. ine guides 6 serve to support `each slug above and spaced from the bed plate sufiicient to permit the admission of a card or blank beneath the printing slug. Adyacent the `printing position for the slugs, the guide rails 6 are cut away on their lower edges 62 to permit each card'or blank to pass transversely through them below the slug, as shown in Figs. 3 and 3a.

The plunger 21 passes through an opening O formed in the bed plate to cause pressions from each slug upon a blanifr. Prior to the operation of the plunger 2l, upwardly through the opening a card C is fed through the openings 62 to a position over or above the opening O. W hen so positioned the plunger 21 moves upwardly an d presses the adjacent blank against the printing slug which has been moved into position of registry with the blank. The chain 22 passes through an opening 33 in the fined pressure head 7, as shown in Fig. 5.

Any suitable means may be provided for inking the slugs P. is one example of such means, I have chosen to illustrate a pair of inking rollers 11,11', preferably arranged adjacent to the delivery end of the receptacle 4i, atV one side of the machine. I1`he cards or blanks C are stacked in the receptacle R in superposed order. The cards C are fed `from the receptacle, one by one, through a slot fr by mechanism, which will be later described. 311, 34', indicate a pair of feed rollers which engage the cards as they are fed from the receptacle R and move them across the path of movement of the slugs P toward a second pair of feed rollers 35, 35', which in turn move the cards to a position above second slot or opening '1` formed in the bed plate. @ne feed roller, in each pair of feed rollers, may be loosely mounted on a suitable but the opposite feed roller of each pair is rotated in any well known manner at a speed to insure the feeding o f the cards C to the printing positions in correlation to the movements of the slugs and drum.

36 indicates an idler for holding each card in contact with the type z? upon the printing roller or drum 3 to cause printing on the card as it passes the latter. rihe type t may be secured to the drinn in any preferred manner and supplied, preferably once in each revolution of the drum, with ink by suitable mechanism such as illustrated at 37, 37.

7 indicates openings. preferably two.I formed in the bottom of the receptacle il. r indicates a card feeding member movably mounted in and projecting through each of the openings r. Each feeding member i" is i'ireferably provided with slightly raised nietallic rear edge r2, which may be adjusted by means of screws r3 to conform to the thickness of the blanks C. Upon each feeding member is preferably placed a thin sheet or rubber r4, through which project needle points 175 to provide positive means of engagement with each blank as it is fed forwardly from the receptacle The card feeding members r are preferably given a forward and backward reciprocating movement and also a vertical reciprocating movement and these movements are so timed relatively to eac'h other that the rear ends of the cards are raised before the forward movement commences, thereby eliminating any tendency of the cards to adhere together during the forward movement thereof conjointly with the movement of the feeding members r; frs a result of this operation, the lower-most card is caused to readily disengage itself from the cards in the stack for feeding by the feeding members r to the feed rollers 34, 34. The feeding members then recede to a position below the bottom 1" of the receptacle R and thereafter move rearwardly to a position to engage the next card in the stack.

1When a card is fed from the receptacle it is engaged by the first pair of feeding rolls 34, 34 and is thereby propelled underneath the guides 6, 6 through the openings 6? therein to the printing position for the printing slugs. The card remains in this position until a second card is fed from the receptacle, which engages the rear end of the forward card and pushes it between the second set of feeding rollers 35, 35', which in turn propel the card to the printing position for the printing drum 3. Tie drum 3 impresses the main subject matter successively on the cards. The mechanism for obtaining these results may be described as follows:

40 indicates a pair of eccentrics mounted in any suitable manner on the shaft 13. 41 indicates a pair of thrust members each connected at one end to and operated by the adjacent eccentric40. At its opposite end each thrust member 41 is connected to a lever 42, which is pivotally mounted at its lower end in any preferred manner upon a depending member of the bed plate l. 43 indicates devices which are pivotally connected to the upper ends of the levers 42 and reciprocated thereby. 45, 46, indicate pairs of toggle members. The inner ends of the toggle members are connected to the reciprocatable devices 43, while their outer ends are connected to the feeding members r and sliding members 49. The sliding members are preferably mounted to move on suitable guides provided on the bed plate l, as shown in Fig. 8. The thrust members 4l are actuated by the eccentrics to oscillate the levers 42, which in turn reciprocate the devices 4!" As the devices 43 move forward, the toggle members will be caused to spread or open to the position. shown in Fig. 7. The reaction of the toggle members lagainst the sliding members 49 during such movement causes the feeding members r to rise. After the toggle members have completely opened, they serve to transmit the further movement of the devices 43 to the feeding members r to move the latterv forwardly to feed the adjacent card C in the stack. YWhen the direction of movement of the devices 43 is reversed, the rearward movement thereof operates to close the toggle members 45, 46, which in turn move the feeding members r downwardly relative to the bottom r? and to thereafter move the feeding members -r rearwardly to their initial position.

The links 4G may be made longer than the links 45. llhen so constructed a greater elevation is imparted to the rear extremities of the feeding supports or members when the'devices 43 move forwardly; when the devices 43 move rearwardly the feeding supports are lowered below the level of the bottom plate of the receptacle so as to clear the cards entirely. The rear wall of the receptacle is preferably inclined at I so that the rear end of the bottom card will be spaced from the rear end of the card above and thus give access to the engaging edges r2 of the feeding supports and prevent them from engaging more than one card.

Additional mechanism is preferably provided to agitate the cards and to relieve friction upon the bottom card so that they will feed more easily. This is accomplished by hinging the upper portions of the front and rear walls of the receptacle R at 1V lV and providing means for throwing or swingforward these walls at their upper ends as each card is being fed from the receptacle as shown in Figs. 5 and 7.

Of this mechanism X, X, indicate arms projecting rearwardly and upwardly from the links 43 and connected at their upper ends, by means of links X', X with the rear wall V, whereby the latter will be swung forwardly, on the adjacent pivot 1V, as shown in dotted lines in Fig. 7, each time the devices 43 reciprocate. The front and rear walls V, V', are connected together by means of links V2 so as to move in unison.

The operation of the walls V, V', about their pivots lV, will shift the cards in the stack above the plane of the pivots 1V forwardly, so that their forward edges will be supported by the front wall V. The effect of this operation is to relieve the lowermost card in the stack of the weight of the cards in the upper part thereof, particularly along the front e lge of the lowermost card as it is being fed forwardly. As shown in Fig. 6, the front and rear walls V, V, extend from side wal1 'o side' wall of the receptacle R and move i., wardly and rearwardly thereetween. As the side walls are maintained f tained in stationary, the caids or blanks C are mainposition to be fed forward for printing.

. The feeding rolls 34, 84 are operated by means of spur gears 50 and 51 upon shafts 13 and 52 and the feeding rolls 35, 35 are operated by means of gears 9, 54C and 55 upon shafts 56, 57 and main shaft 2, respectively. Y

The second pair of feeding rolls are preferably operated ata higher rate Vof speed than the first pair of feeding rolls to accommodate the peripheral rate of speed of the printing roll.

To those skilled in the art to which my invention relates, many modifications of and widely differing embodiments and applications of my invention will suggest themselves, without departing from the spirit and scope thereof.
